10 Deepest Lakes In the World

Lake Baikal is the world's oldest and deepest lake; it is the second most voluminous lake, after the Caspian Sea. As the most voluminous freshwater lake in the world, with an average depth of 744.4 m (2,442 ft), Lake Baikal contains roughly 20% of the world's surface fresh water. Located in the south of the Russian region of Siberia (between Irkutsk Oblast to the northwest and the Buryat Republic to the southeast, near the city of Irkutsk), the body of water is also known as the "Pearl of Siberia". At 1,642 metres (5,387 ft), Lake Baikal is the deepest, and among the clearest of all lakes in the world. At more than 25 million years old, Baikal is also the world's oldest lake.
